[Visual Refresh] Add Borealis theme (elastic#199993)

## Summary This PR introduces the first internal version of the new theme `Borealis` and ensures that: - themes can be switched between "Amsterdam" and "Borealis" - theme-specific Sass files are available and can be loaded with `KBN_OPTIMIZER_THEMES=experimental` - legacy JSON variable usage accounts for both themes - static template styles account for both themes ## Running locally ```yml // kibana.dev.yml or kibana.yml uiSettings.experimental.themeSwitcherEnabled: true ``` Start kibana ``` KBN_OPTIMIZER_THEMES='v8light,v8dark,borealislight,borealisdark' yarn start or KBN_OPTIMIZER_THEMES=experimental yarn start ``` ### Checklist - [x] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios - [ ] [Flaky Test Runner](https://ci-stats.kibana.dev/trigger_flaky_test_runner/1) was used on any tests changed --------- Co-authored-by: Tomasz Kajtoch <[email protected]>
